SCENARIO 10-13
The amount of time required to reach a customer service representative has a huge impact on customer satisfaction.Below is the Excel output from a study to see whether there is evidence of a difference in the mean amounts of time required to reach a customer service representative between two hotels.Assume that the population variances in the amount of time for the two hotels are not equal.
t-Test: Two-Sample Assuming Unequal Variances

Two-Sample Tests 10-41

Quizplus · Accepted Answer

The critical value for a hypothesis test at a significance level of 0.05, assuming a normal distribution and a two-tailed test, is approximately ±2.0244. This corresponds to the z-values that cut off the outer 5% of the distribution, split into 2.5% in each tail.
